Introduction: Christmas Tree With LED and Music, Controlled With Arduino

About: I'm an Arduino Maker, I like technology, playing tennis

In this holiday season, almost everyone has done their Christmas tree in your home, small or large. In this post, we will see how to create a Christmas tree with a few €, using Arduino. Through this microcontroller will be able to choose from several different profiles, which allow you to sing and illuminate our "tree".

What do you need?

Arduino Uno 
Infrared remote control 
Box Pandore / Panettone 
Felt-tip pens or watercolors 

Step 1: Explanation of the Project

Explanation of the project

At the base of the project, there are several components, each with a specific goal:


The LEDs are simply diodes that light up when there is a current step, typically a few tens of mA. The potential drop between the anode and cathode is typically a few volts


This device allows you to play the Arduino through a current flow in the device. Through the calculation of the period of a particular note, you can play it with your device. Here's the full list:

Step 2: Infrared Remote Control

Infrared remote control

This device has the task of deciding what kind of song you play. Pressing one of the buttons on the remote control, the receiver located a few meters, you can send a binary encoding to the Arduino, which establishes the point of the Arduino code to be executed.

Here is a list of the remote control code for the Arduino:

Step 3: Steps for the Realization

Steps for the realization

Take a carton of a Pandoro / Panettone
Paint it with a color of green
Arrange the LEDs around the box
Also connect the buzzer outside
Connect the IR receiver inside the Pandora
Connect the anode and cathode of the LEDs, respectively, selected PIN and to GROUND
Load the program on Arduino

You can download the program of Arduino from my Github repo

Step 4: Final Risult

As you can see from this video, the result is pretty good ! It is a very good project with Arduino !
